Filed May 11, 1960, Ser. No. 28,445 4 Claims. (Cl. 15119) The object of this invention is to devise a novel mop having novel extracting mechanism and wherein a novel extractor in the form of a split ring is pivotally connected at its outer periphery with a longitudinally movable actuating rod; said extractor after a forward extracting stroke is moved rearwardly over the mop head to be positioned above the mop handle, and a cam at the rear end of the mop head on the forward stroke is contacted by the extractor to cause the extractor to move over the mop handle into longitudinal alignment with the mop head into position for the forward extracting stroke of the extractor.

For the purpose of illustrating the invention, we have shown in the accompanying drawings preferred embodi ments of it which we have found in practice to give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limited, except by the scope of the appended claims, to the exact arrangement and organization of these instrumentalities as hereinset forth.

FIGURE 1 is a top plan view of a strand type mop and extracting mechanism, embodying our invention.

FIGURE 2 is a section on line 2-2 of FIGURE 1.

FIGURE 3 is a side elevation of the front portion of the mop with the extractor in section and contacting a positioning cam.

FIGURE 4 is a side elevation with the extractor in section and with the parts in the positions they assume just before the completion of the extracting operation.

FIGURE 5 is a side elevation with the extractor in section and in a position which it assumes on its rearward movement.

Referring to the drawings:

The mop head 1 is connected with a handle 2 in such a manner that it can be replaced with a new mop head when the original mop head becomes worn.

The mop head consists of absorbent strands 3 secured in mop head formation by a U-shaped clip surrounding the central portions of the strands as shown at 4 with the ends of the clip passing through a crossbar 5 and then bent forwardly at an angle to receive a cap sleeve 6 which may be plastic and frictionally interlock therewith. The forward end of the handle has a genena-llyrectangular formation which passes through a rectangularly shaped opening in the cap sleeve and terminates in a threaded end in threaded engagement with a threaded opening in the crossbar 5 as shown at 7. As herein shown, the handle has its front portion for-med by a bar 8 which may have opposite sides tapering upwardly, and the rear end of the bar is fixed in a plug 9 secured in a tubular portion of the handle.

We preferably but not necessarily employ a plastic cam 10 having a rectangular opening to receive the bar 8. This cam may have a friction fit on the bar and abuts against the cap sleeve or secured thereto by adhesive (see FIGS. 1 to 4) or the cap sleeve and cam may be formed in one piece as shown in FIGURE 9, the sleeve being indicated at.1*1 and the cam at 12. The rear face of the cam is inclined to the longitudinal axis of the mop handle.

The cam face is formed by two intersecting planes providing a ridge that'lies in the plane of the handle.

The extractor 13 has closed top and sides with a slit or slot 14 at its bottom, and has an opening 15 the contour of which corresponds to the shape of the mop head, which as shown is round but which might have a conventional rectangular or other shape. The extractor is of flexible plastic material and the sides preferably curve downwardly towards its slot. The upper end of the extractor is bifurcated to receive the front end of an extractor rod 16 whichis pivoted thereto at 17, and has a clearance in a guide 18 fixed to the handle. This guide maybe integral with the handle as shown in FIGURE 8 with a rod 19, guide 20 and handle 21. The inner end of the extractor rod 16 is bent downwardly and pivoted at 22 to a grasping handle 23 longitudinally movable on the handle 2.

The bifurcation of the extractor to provide for its pivotal connection with its actuating rod forms a shoulder which contacts the rod to limit the extent of the rearward swinging movement of the extractor during the extracting stroke. See FIG. 4.

If desiredU-shaped springs 24- may be mounted on the extractor to restrict its expansion but this can be omitted if the sides of the extractor have the requisite flexibility.

In the operation, when the extractor is in the position seen in FIGURE 2 the extractor rests on the bar 8, having swung downwardly due to its pivotal support and its own Weight. The operator now pushes the handle 23 forwardly and the cam 10 causes the extractor to open and pass below the bar 8 into the position shown in FIG- URE 3. The continued forward movement of the handle 23 moves the extractor over the mop strands as shown in FIGURE 4. After the completion of the forward stroke, the handle 23. is moved rearwardly, and the extractor rides over the mop head as in FIGURE 5 and returns to the position shown in FIGURES 1 and 2 ready for the extracting operation. The extractor may have its outer wall of any desired contour, but since a round type strand mop ha'sbeen shown the extractor is illustrated as a split ring.

Due to clearance in its guide, the rod 16 is permitted to move upwardly.

Due to the extractor being inclined prior to its positioning for forward movement it will be noted that if the cam is omitted, the lower end of the extractor will contact the cap sleeve and force the extractor downwardly since in both cases an abutment is provided against which the lower end of the extractor will contact.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. The combination with a mop having a mop head and a mop handle, of extracting mechanism, comprising a hollow extractor member having a slot to permit it to pass over the mop handle into alignment with the mop head, an extractor rod pivotally connected at its front end with said member and longitudinally movable alongside of the mop handle, a guide on the mop handle through which the rod passes, and a sleeve longitudinally movable on the mop handle and connected with the rear end of said rod, said member after an extracting stroke riding rearwardly over the mop head and after passing Patented June 26, 1962 the mop head pivoting into contact with the mop handle, and said member on its forward extracting stroke contacting the rear end of the mop head to cause the member to pass over the mop handle into alignment with the mop head.

2. The construction defined in claim 1, wherein the rear of the mop head has a cam face which is inclined relative to the longitudinal axis of the mop handle.

3. The construction defined in claim 1, wherein the rear end of the mop head is formed by a cap cylinder and a cam is on the mop handle in rear of the cap cylinder.

4. The construction defined in claim 1, wherein the extractor member and its rod have cooperating surfaces 'to limit the extent of pivoting movement of the member on its extractor rod.
